We love our black and white monochrome displays but we also like to
dabble with some color now and then. Our 1.27" color OLED displays are
perfect when you need a small display with vivid, high-contrast
color. The visible portion of the OLED measures 1.27" diagonal and
contains 128x96 RGB pixels, each one made of red, green and blue
OLEDs. Each pixel can be set with 16-bits of resolution for a large
range of colors. Because the display uses OLEDs, there is no
backlight, and the contrast is very high (black is really black). We
picked this display for its excellent color, this is the nicest mini
OLED we could find!
This OLED uses the SSD1351 driver chip, which manages the display.
You can talk to the driver chip using 4-wire write-only SPI (clock,
data, chip select, data/command and an optional reset pin). Included
on the fully assembled breakout is the OLED display and a small boost
converter (required for providing 12V to the OLED) and a microSD card
holder. This design includes built-in logic level shifting so you can
use it with 3-5VDC power and logic levels. Our example code shows how
to read a bitmap from the uSD card and display it all via SPI.
Of course, we wouldn't just leave you with a datasheet and a "good
luck!" - we\'ve written a full open source graphics library that can
draw pixels, lines, rectangles, circles, text and bitmaps as well as
example code . The code is written for Arduino but can be easily
ported to your favorite microcontroller! We do not have a detailed
wiring tutorial at this time, but if you follow the example code
wiring it should work just fine.
* 1.27" diagonal OLED, 16-bit color
* SPI interface
* 3.3-5V logic and power
* PCB Dimensions: 36mm x 43mm/1.4" x 1.7" / 2mm thick
* Screen Dimensions: 32mm x 27mm/1.27" x 1.07"
* Display current draw is completely dependent on your usage: each
OLED LED draws current when on so the more pixels you have lit, the
more current is used. They tend to draw ~30mA or so in practice but
for precise numbers you must measure the current in your usage
circuit. This does not include the SD card, which is separate
